## Tools (as reported by the server, not verified)

- `list\_categories`: List the product categories that have a published tier list, newest research first. Call this first when you do not already know the exact category slug: slugs cannot be guessed reliably and every other tool takes one.
- `search\_products`: Find ranked products by name or brand across every board. Returns the slug, category and tier for each match, which is what get\_product and get\_tier\_list need next.
- `get\_tier\_list`: The full S-to-F tier list for one category: every ranked product with its tier, rank, LP, verdict, pros, cons, citation counts, GTIN barcodes and, where the maker published one, the announcement date. This is the primary tool and one call answers a "what is the best X" question completely. Call get\_
- `get\_product`: Everything held on one product: its placement, verdict, pros and cons, GTIN barcodes, the announcement date where the maker published one, and a breakdown of how the cited sources read \(how many were glowing, positive, neutral or negative, and whether they were outlets, named authors, video channels
- `compare\_products`: Compare two to five products side by side. They must share a category: LP is points on one category ladder and comparing across boards is meaningless, so a mixed request is refused rather than answered misleadingly.
- `what\_to\_avoid`: The products the research placed in the bottom tiers, and the ones it deliberately entered as traps buyers cross-shop but should not buy. Use it to answer "what should I not buy" and to check whether a product a user is considering was flagged.
